If you vertically compress the absolute value parent function, f(x) = |x|, by a factor of 3, what is the equation of the new function?

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
